Pluggable fuel gas power air conditioning system used for hybrid power and pure electric buses

Abstract

The invention relates to a pluggable fuel gas power air conditioning system used for hybrid power and pure electric buses and belongs to the technical field of new energy bus electrical appliance accessory application. The air conditioning system comprises a gas storage tank, a gas engine, a compressor, an electric generator, a cooling fan, a blower, a condenser, a throttle expansion valve, an evaporator, a stock solution dry filter, a temperature sensor and an air conditioner controller, wherein the compressor and the electric generator are driven by the gas engine, the electric generator provides electric power to enable the cooling fan and the blower to work normally, the condenser, the throttle expansion valve, the evaporator, the stock solution dry filter, the temperature sensor and the air conditioner control are connected in sequence through pipelines and the compressor, the temperature sensor is used for collecting temperature signals, the air conditioner controller is used for controlling journey work of an air conditioner. The air conditioning system is installed on a vehicle roof without the need for taking power from a vehicle-mounted battery, and battery cost can be reduced by 30% in a whole vehicle production process. Plugging into and pulling out of the whole vehicle can be achieved through assembly and disassembly, when not needed, the air conditioner can be disassembled, when the air conditioner is not needed, extra loads of the vehicle are relieved, and energy consumption in driving is reduced.

Description

technical field [0001] The invention relates to a pluggable gas-powered air-conditioning system for hybrid and pure electric passenger cars, and belongs to the technical field of application of electrical accessories for new energy passenger cars. Background technique [0002] For some current hybrid electric passenger cars, the air-conditioning system is powered by a generator driven by the engine. Therefore, when the development and design parameters of the passenger car are matched, the air conditioning system increases the demand for the maximum power of the engine and increases the production cost of the passenger car; The economy is poor. [0003] For some hybrid electric buses and pure electric buses, the air conditioner is powered by the on-board battery pack, which causes the battery capacity design to take into account the power demand of the air conditioner during vehicle development and design, resulting in higher battery costs during vehicle development. Using...
